Not just from a vulnerability poerspective but also a dev and testing perspective. Constant updates makes testing far more involved for every release since you can't just focus on the parts the dev work would have affected, you also need to thoroughly test everything that was calling into the updated dependency. But if you don't update enough, once you really do need to update either for security or feature reasons, you may have a nightmarish process ahead of you of dealing with breaking changes and transitive dependency incompatibilities.
